Q: With the Zeltiq Procedure Why Does only 25% of the Fat Die?

Q: Zeltiq supposedly yields a 25% reduction of fat in the areas treated. But if Zeltiq chills all the fat to the same temperature, then why does only 25% of it die? Does the fat immediately under the skin die the most, since it's closest to the cold source? If so, how can there not be problems with sagging skin?

A: The cooling mechanism does affect the superficial fat more than the deep fat so as a result, the majority of fat removal occurs closer to the skin. As the reduction of overall fat is approximately 25% and evenly distributed, the technique has not been found to create sagging skin. If a patient has preexisting saggy skin, Zeltiq will not improve the condition as it is not a skin tightening technique.Google+
